Testing for lead in drinking water at some Minnesota schools hasn’t been done since the late 1990s, despite a state health recommendation that it take place every five years.
Among records for more than 600 schools, at least 1 in 4 are not testing properly.
Records show that the Minneapolis district hasn’t tested at least 31 of its schools since 1998, though district officials say they are following the state’s guidelines for flushing water lines to reduce lead levels.
